"When you activate Windows XP, Microsoft stores the data in the Windows
Product Activation database files wpa.dbl and Wpa.bak in the folder %systemroot%system32.
If you change the motherboard or make significant hardware changes, XP will
require you to reactive. But if you plan to reinstall XP on the same hardware,
you can back up the activation status and then restore it after you reinstall
and avoid the activation process."
